Do fish know if it’s going to be a cold winter? You may hear that groundhogs can predict (预测) the end of the winter. Some of the sayings, like, “if a cat sits with its back to the fire, hard weather can be expected.” may sound unbelievable, but some may be true. Many animals do have stronger senses than humans. Do animals tell us when a storm is coming? Birds react to the drop in air pressure (气压) before a storm by flying low. Insects stay close to the ground and wolves howl because their ears can sense the pressure change. A good rule is, when animals act strangely, you probably should be careful with the environment (环境) around us. Do you know the sound of crickets’ chirping (鸣叫) can tell you how hot the day is? Crickets are cold-blooded, so when the temperature in the air changes, the cricket’s body temperature changes with it. As the temperature rises, the cricket’s metabolism (新陈代谢) increases. When the heat rises, crickets chirp. To get the exact temperature in degrees Fahrenheit (℉), count the number of chirps in 14 seconds, and add 40. Do you have a tried and true weather animal that predicts the weather? 回答下列5个问题，每题答案不超过6个词。 1. Why can some animals know the weather changes? __________________________________ 2. What do birds do before the storm? __________________________________ 3. When should we be careful with the environment? __________________________________ 4.
